Mark Abraham (Vajramuni), an epigraphist and linguistic expert, discovers the writings of an explorer about the Bherunda kingdom's treasure and becomes determined to retrieve it.
They are joined by Jai (Amrish Puri), a geologist, who informs Abraham that he has located the site where the shipwreck containing the treasure is buried on the island of "Hasta Dweepa."
However, Abraham, unwilling to share the wealth, kills Chanda and the rest of the crew on the boat, leaving Raju and Bijju wounded on the island.
The brothers are rescued by Nayar (Shankar Nag), an islander who lives with his dog, Manja.The three return to the mainland and begin a new life, though they continue to harbor a grudge against Abraham.
Two years later, while working on a new project, Raju and Bijju uncover a trunk containing an ancient vase, which proves to be part of the treasure of Bherunda.
Abraham arrives with his team, having killed his crew and assistants, except for Myna, whom he stabs in the stomach on Jai's insistence, so that they share the wealth.
